HELP PLS I WILL GIVE LOTS OF POINTS pls answer good and i will give brainliest and give more points if its correct
Fofino [41]

Answer: .374 and .626

Explanation:

5. total number of alleles = 4712 + 2816 = 7528

       frequencey of B allele = B allele / total number of alleles --> 2816/7528 = 0.374                

             

6. total number of alleles =  4712 + 2816 = 7528

   freq of b allele = b allele/total number of alleles --> 4712/7528 = 0.626

We can confirm our answer as correct because if we add up the answers to 5 and 6 we should get one:

0.374 + 0.626 = 1

What happens when a cold front replaces a warm front
frozen [14]

Answer:

When a cold front overtakes a warm front, it creates what's called an occluded front that forces warm air above a frontal boundary of cooler air masses.

Explanation:

The presence of a cold front means that cold air is advancing and pushing underneath warmer air. This is because the cold air is ‘heavier,’ or denser, than the warm air. Cold air is thus replacing warm air at the surface.

HELP
Tanzania [10]

Answer:

Photosynthesis produces: <em>glucose </em><em>and </em> O_{2}

                 ...from  CO_{2}, energy (light) and H_{2} O

Respiration produces: energy (ATP),CO_{2}, H_{2} O  

                ....from <em>glucose </em><em>and  </em>O_{2}<em />

<em />

Explanation:

These end products, namely O_{2} and glucose are then used in respiration...

Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.

They combine light energy from the sun, water, and carbon dioxide.

6CO_{2} + 6H_{2} O + (energy) →C_{6} H_{12} O_{6} + 6O_{2}

In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

<h3>C_{6} H_{12} O_{6} + 6 O_{2}  _{\to \ 6CO_{2} + H_{2} O + energy (ATP)</h3>

The waste products, CO_{2} and H_{2} O,  result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants O_{2}  and C_{6} H_{12} O_{6} in respiration.
